What is the role of the microbiome in human health and disease?

The human microbiome, consisting of trillions of microorganisms (bacteria, viruses, fungi, and archaea) living in and on the body, plays a crucial role in maintaining health. It helps digest food, synthesizes essential vitamins, modulates the immune system, and protects against pathogenic microorganisms by competing for resources. Dysbiosis, or an imbalance in the microbiome, has been linked to various diseases, including inflammatory bowel disease, obesity, diabetes, and even mental health disorders. Understanding the microbiome’s role opens up new possibilities for targeted therapies and probiotics to restore health.
